              Application:

              With proper HLB value and high safety, PP can be used as ingredient of household/ industrial cleansers. It can also be used as high polymer solvent in water-soluble / solvent-type coating.

              DPP is mainly used as industrial solvent, water-based coating, ink and cleanser. As a good coupling agent, it can replace alcohol solvent in the dissolving process of dyestuff. Some formulas can be changed to be water-soluble by applying propylene glycol ether in ink production to lower the ink toxicity and improve operating environment. The propylene glycol ether can be used to make various condensate cleansers.
